Conformal Spectrum and Harmonic Maps [PDF]
Moscow Mathematical Journal, 2015 This paper is devoted to the study of the conformal spectrum (and more precisely the first eigenvalue) of the Laplace-Beltrami operator on a smooth connected compact Riemannian surface without boundary, endowed with a conformal class.

Boundary conformal anomalies on hyperbolic spaces and Euclidean balls [PDF]
Journal of High Energy Physics, 2017 We compute conformal anomalies for conformal field theories with free conformal scalars and massless spin 1/2 fields in hyperbolic space ℍ d and in the ball Bd $$ {\mathbb{B}}^d $$, for 2≤d≤7. These spaces are related by a conformal transformation.

Representation of conformal maps by rational functions [PDF]
Numerische Mathematik, 2018 The traditional view in numerical conformal mapping is that once the boundary correspondence function has been found, the map and its inverse can be evaluated by contour integrals.

Celestial diamonds: conformal multiplets in celestial CFT [PDF]
Journal of High Energy Physics, 2021 We examine the structure of global conformal multiplets in 2D celestial CFT. For a 4D bulk theory containing massless particles of spin s = 0 1 2 1 3 2 2 $$ \left\{0,\frac{1}{2},1,\frac{3}{2},2\right\} $$ we classify and construct all SL(2,ℂ) primary ...

A factorization of a super-conformal map
, 2012 A super-conformal map and a minimal surface are factored into a product of two maps by modeling the Euclidean four-space and the complex Euclidean plane on the set of all quaternions. One of these two maps is a holomorphic map or a meromorphic map. These

The Map Between Conformal Hypercomplex/ Hyper-Kähler and Quaternionic(-Kähler) Geometry [PDF]
, 2004 We review the general properties of target spaces of hypermultiplets, which are quaternionic-like manifolds, and discuss the relations between these manifolds and their symmetry generators.

A new approach to calculating fiber fields in 2D vessel cross sections using conformal maps
Mathematical Biosciences and Engineering, 2023 An arterial vessel has three layers, namely, the intima, the media and the adventitia. Each of these layers is modeled to have two families of strain-stiffening collagen fibers that are transversely helical. In an unloaded configuration, these fibers are

Computing Quasiconformal Maps on Riemann surfaces using Discrete Curvature Flow [PDF]
arXiv, 2010 Surface mapping plays an important role in geometric processing. They induce both area and angular distortions. If the angular distortion is bounded, the mapping is called a {\it quasi-conformal} map. Many surface maps in our physical world are quasi-conformal. The angular distortion of a quasi-conformal map can be represented by Beltrami differentials.
